The girl's father has registered a case against four persons, Saharanpur SSP Nitin Tiwari said.
According to the complaint, the incident occurred when the 14-year-girl was sleeping with her grandmother in her home at Sankror village in Lakhnauti last night, the SSP said.
Thereafter, two men came to the girl's house, stuffed her grandmother's mouth with a cloth and tied her to a cot, Tiwari said citing the complaint.
The two accused then allegedly took the girl to a nearby orchard, where they along with two of their accomplices, gang-raped her, the father said in the complaint.
The family members found the girl in a nearby orchard at around 4 am.
The victim has been sent for medical examination and efforts are being made to nab the accused, police said.
